Well I just installed the unbelievably cheap ZX8-CCB composite video mod, and it’s awesome. It did need a little tweaking on the presets to get over a completely black screen, but the video quality is second to none on this unbelievably cheap (£5.80+£1.90P&P) bit of kit. Other mods are available but at 5x the price. If you want one, check out http://www.sellmyretro.com/offer/details/3712
